That is the Decel Valve. http://home.sprynet.com/~dale02/decel.htm Mine leaked, so I removed it.

FWIW, the EGR and Charcoal canister do not hurt performance or fuel economy in any way. The only benefit of removing them is to pollute more.

I vaguely remember that Maryland is like we are here in Missouri, that they check for the EGR valve and Charcoal Canister as a part of the safety inspection. I would double check that.

The vacuum advance for the distributor is supposed to be on a ported line. Quick way to test the line its on...start the motor, take the vac line off going to the dist., if the tube that you took the line off of has any vac, then its the wrong tube.

Vacuum advance works to advance timing when you are on the throttle, NOT when you are idling. If the motor is at an idle, the line going to the dist wont have any vacuum on it.


Could that be why im not idleing? And have to feather the gas to stay running

Most of us on the CJ board run manifold vacuum for its many benefits over ported vacuum. I'd keep it on manifold vacuum, especially with a smaller 32/36.

Manifold vac is better for your engine and drivability
